┗━Activity Android

  

MainActivity.java 
 
package com.example.liguofeng.requestdatatoactivity;

import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button login = (Button) findViewById(R.id.login);
        login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String account = ((EditText) findViewById(R.id.account)).getText().toString();
                String password = ((EditText) findViewById(R.id.password)).getText().toString();

                // Bundle
                Bundle data = new Bundle();
                data.putString("account", account);
                data.putString("password", password);
                // Intent&Activity起動
                Intent intent = new Intent(MainActivity.this, SecondActivity.class);
                intent.putExtras(data);
                startActivity(intent);
            }
        });
    }
}

 

SecondActivity.java 
 
package com.example.liguofeng.requestdatatoactivity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;

import org.w3c.dom.Text;

public class SecondActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.second);

        TextView account = (TextView) findViewById(R.id.rls_account);
        TextView password = (TextView) findViewById(R.id.rls_password);

        // 起動時のIntent取得
        Intent intent = getIntent();
        // Intent内のデータ取得
        account.setText(intent.getStringExtra("account"));
        password.setText(intent.getStringExtra("password"));
    }
}
